Just one male halfmoon betta in a 3.5 gallon tank, two 50% changes each week. It's filtered - you can see the canister in the back, wish I'd thought better of how to hide it. I'm thinking of getting some Anubias petite to put on top of the rocks.

Edit: I really want to get a second tank with either wilds or an HMPK male, but since I'm in my final year of uni and going for a masters degree plus internship directly after, I may not have the time required for upkeep :(

I might put in a solid-coloured background, that's a good idea, Aokashi :)

Technically, if I were to buy new, longer tubing, I could put the filter underneath the table, but the filter's instruction manual says to place it at the same level as the base of the tank. I'm not entirely sure if this is necessary, because I've seen some people with the exact same model of filter doing the opposite of that.
